HIGHLANDS, NJ — Great whites Finn and Amagansett are making a break for it, as they leave the waters off the New Jersey coast and head north.
Both young females are about 30 miles off Highlands traveling northward, as Finn registered his last ping at 11:26 a.m. on September 18 and Amagansett at 10:30 p.m. on September 14, according to Ocearch’s Global Shark Tracker.
Shortly after being tagged on August 12 off Montauk, N.Y., Finn began traveling south and settled off the coast along Monmouth County on September 1, where he stayed before his latest move to go north.
After being tagged on August 20 also off Montauk, Amagansett followed a similar path but traveled farther south, circling around the waters off the Ocean County coast before making the pivot northbound.
When both juvenile females were tagged by Ocearch researchers, Finn measured nearly 5 feet and weighed 79 pounds, and Amagansett came in at nearly 5½ feet and 92 pounds.
Meanwhile, Mary Lee — the 16-foot, 3,500-pound shark that became a social media sensation this spring with her travel adventures in the Atlantic Ocean off New Jersey — registered her last ping at 6:54 a.m. on June 17 about 10 miles off Long Beach Island.
Since Mary Lee was tagged off Cape Cod, Mass., on September 17, 2012, she has traveled up and down the East Coast — from Nova Scotia to the Turks and Caicos Islands — for a total of some 40,000 miles.
All three great white sharks are among dozens of apex predators throughout the world that have been tagged by Ocearch researchers with global positioning satellite (GPS) devices in order to track their movements to better understand their behaviors.
Ocearch registers a ping when the shark’s dorsal fin breaks through the water, transmitting a signal that provides an estimated location. The group then displays a marker on a Google Earth map indicating where the ping was received.
Based in Park City, Utah, Ocearch is the leader in generating critical scientific data related to tracking (telemetry) and biological studies of keystone marine species, such as great white and tiger sharks.
